I tested this by switching to a console from the installer in text mode.
Despite I specified in the installer that the partitions were of type
'fd'. According to what I was checking after to switching to the
console, the installer did not make the corresponding changes in the
partitions so I had to manually make changes with fdisk. Then I created
md devices making second member is 'missed'.
But to return to the partitioner of the installer in text mode, this did
not take the changes. Even going a step back and choosing a custom
design, I can not see the md devices created through the console.
Have I to perform some additional operations to take the changes in the
installer?
Thanks for your replies.

Daniel
